Alcohol use, alcohol use disorder and heavy episodic drinking in the Eastern Mediterranean region: A systematic review.

BACKGROUND AND AMS: Despite the evident public health impact, the extent and patterns of alcohol use in the Eastern Mediterranean countries remain understudied. The latest estimation for the last 12-month use of alcohol in the region was 2.9% in 2016 by the World Health Organization. We reviewed the main indicators for alcohol consumption in the region since 2010. METHODS: We systematically searched on-line databases until September 2023, together with other global and regional sources for studies on the adult general population (aged ≥ 15 years) and young general populations (aged < 18 years) and studies on the treatment-seeking individuals with substance use in Eastern Mediterranean countries. Studies were included from 22 countries: Afghanistan, Bahrain, Djibouti, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Pakistan, Palestine, Qatar, Saudi Arabia, Somalia, Sudan, Syria, Tunisia, United Arab Emirates and Yemen. RESULTS: A total of 148 were included (n = 95 on the prevalence of alcohol use, n = 46 on the prevalence of alcohol use disorder, regular use and heavy episodic drinking, n = 35 on alcohol use pattern among people who use substances and one report on alcohol per capita consumption, n = 29 had data for more than one category). The pooled prevalence of the last 12-month alcohol use in the adult general population was 9.5% [95% confidence interval (CI) = 6.4-13.7] among males, 2.8% (95% CI = 1.3-5.5\) among females and 6.2% (95% CI = 3.9-9.6) in both sexes in the region, with notable subregional variations. Data on the prevalence of alcohol use disorder and heavy drinking were limited to several countries, with heterogeneous indicators. The pooled estimate of alcohol as the primary substance of use among treatment-seeking people who used substances was 16.9% (95% CI = 8.8-26.9). CONCLUSIONS: More than 30 million adults in the Eastern Mediterranean region used alcohol in the last 12 months, with a prevalence of 6.2%. This is far fewer than the global estimate of 43% of the population aged 15 years and above, but is approximately two times more than the previous estimate (2.9%), reported by the World Health Organization in 2016, which might show an increasing trend.

Designing and Evaluating the Validity and Reliability of the Persian Gambling Disorder Screening Questionnaire.

BACKGROUND: Gambling disorder (GD) and substance use disorder (SUD) have mutual impact and each could aggravate the effects of the other. This is the first study on GD among Iranian substance users to develop and validate a GD Screening Questionnaire-Persian (GDSQ-P). METHODS: Iranian male adults (n = 503) with SUDs were recruited via clustered sampling. Problem gambling screening instruments and Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5) criteria for GD were used to develop the tool which was sequentially assessed for face validity, content validity index (CVI), content validity ratio (CVR), and reliability (Kuder-Richardson coefficient). To establish construct validity, interviews based on DSM-5 as a gold standard method were used. A receiver operating characteristic (ROC) curve was conducted to determine sensitivity and specificity. FINDINGS: After removing items with low CVI values, 27 final items remained in GDSQ-P with impact score greater than 1.5. Card games (33.8%), dice gambling methods (26.6%), betting on sports teams and players (24.1%), and betting on horseback, rooster, pigeon, dog, or other animals (16.7%) were common gambling methods among participants. Overall Kuder-Richardson coefficient was 0.95. Cut-off threshold for GDSQ-P was calculated as 4.5 with 98.9% sensitivity and 98.3% specificity. The interviewers confirmed GD for participants based on DSM-5 as the gold standard. The prevalence of GD among participants was 17.9% based on GDSQ-P and 19.1% based on DSM-5 criteria. CONCLUSION: GDSQ-P is a valid and reliable tool to screen for GD in SUD treatment centers and probably in the general population.
